IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 28,576, dated June 5,1860.

My invention relates to a new and improved.

arrangement and construction of the dilferent parts of a cultivator,whereby it may be readily adapted either for one or two horses, and whenfor one either with or without shafts.

To enable others skilled in the art to make, construct, and use myimprovement, I will now proceed to describe it in detail, omitting aparticular description of such parts as are not essential to a fullunderstanding of my improvement.

In the accompanying drawings, the framework of the machine isrepresented as consisting of side beams, D, connected together by meansof cross-beams E. On the ends of these cross-beams are formed tenons forthe purpose of taking into corresponding mortises made in shafts (J, apin, 2, being passed through the tenon on the outsideofthe shaft toretain them in place.

To the cross-beams E, and at or near their center, is secured, by meansof bolts 13, a removable center beam, A,'which is removed from themachine, and a shorter one, similar to the side beams, D, attached, whenit is desired to use the shafts (3 instead of the center beam, A. Tothese side and center beams are secured cultivator -teeth F or double'moldboards, as the case may be, bolts H passing through them and thebeams to keep them in place a wedge, where deemed necessary, being alsodriven in, either in front or behind, to steady them and at the sametime give them the proper set, the cultivator-shanks for these purposesbeing passed through mortises in the beams. On the front cross-beam, E,are erected and secured the handles that guide the machine, they beingsupported and steadied by braces F, erected on the rear cross-beam, E.

When it is desired to useacenter dragbeam instead of the shafts thelatter may be removed by taking out the pins 2 and withdrawing them fromthe tenons of the cross-beams E, in which event the short center beam,like the side beams, D, is detached from the machine, and the longcenter beam, A, as represented in the drawings, applied thereto, andfirmly secured to the cross-beams E by the bolts B, in which event anadjustable guide, G, is attached to the center beam by means of a pinpassing through it and the beam, there being abeam, P, pivoted to thelower end of the adjustable guide G, and having several openings piercedin its sides, through which and an opening in the center beam somedistancein the rear of the guide is passed a bolt, by means of which andthe series of openings in the beam P the angle of the guide to thecenter beam may be varied at will, so as to regulate the depth at whichit is required the teeth or mold-boards should penetrate the soil, theguide G also serving the purpose of steadying the machine andpreventinglateral deflection.

Through the forward end of the center beam is arranged a bolt-hole, bymeans of which and suitable single-trees either one or two horses may beattached for the operation of the machine.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- The peculiar arrangement and combinationof the removable shafts O,center beam, A,and guide G with acultivator,the whole being constructed and operated in the manner andfor the purposes set forth.
